Estimating the sensitivity of the IceCube Upgrade to probe the interior of the Earth using atmospheric neutrino oscillations
The IceCube Collaboration, R. Abbasi, M. Ackermann +421
The IceCube Upgrade is a densely instrumented central region of the IceCube Neutrino Observatory, deployed during the 2025-26 polar season. It will reduce the detector's energy thr…
New constraints on non-unitary neutrino mixing from 8 years of IceCube DeepCore atmospheric neutrino data
Sharmistha Chattopadhyay, Anil Kumar, Sanjib Kumar Agarwalla
The mixing between flavor and mass eigenstates of active neutrinos is described by a unitary matrix. However, the presence of additional heavy sterile neutrino states ca…
Study of the internal structure of the Earth using neutrino oscillations at IceCube DeepCore
Sharmistha Chattopadhyay
Earth's mass and internal structure have been primarily studied through gravitational and seismic methods. Neutrinos, however, offer an independent way to explore Earth's interior…
Constraints on the Population of Common Sources of Gravitational Waves and High-Energy Neutrinos with IceCube During the Third Observing Run of the LIGO and Virgo Detectors
DoÄa Veske, Zsuzsa Márka, Albert Zhang
The discovery of joint sources of high-energy neutrinos and gravitational waves has been a primary target for the LIGO, Virgo, KAGRA, and IceCube observatories. The joint detection…
Towards the Composition of sub-PeV Cosmic Rays at IceCube
Julian Saffer
With the implementation of a low-energy trigger, the surface array of the IceCube Neutrino Observatory is able to record cosmic-ray induced air showers with a primary energy of a f…
Demonstrating the ability of IceCube DeepCore to probe Earth's interior with atmospheric neutrino oscillations
Sharmistha Chattopadhyay, Krishnamoorthi J, Anuj Kumar Upadhyay
The IceCube Neutrino Observatory is an optical Cherenkov detector instrumenting one cubic kilometer of ice at the South Pole. The Cherenkov photons emitted following a neutrino int…
